RE: Cisco Call Manager & HP Switches

["Bastian, Tim" <>]

Barry (and others who may be interested),  here is what we are using at Penn
State for our VoIP deployment:

HP ProCurve 4000m switches:
http://www.hp.com/rnd/products/switches/switch4000/overview.htm
 - 100bF uplinks used to redundant routers
 - MAC address locking used to prevent unauthorized devices/moves
 - redundant power supplies to allow UPS maintenance outages
 - CDP mapping
 
Cisco Power Insertion Panels:
http://www.cisco.com/warp/public/cc/so/neso/vvda/iptl/cippp_ds.htm
 - UL and IEC safety measures to prevent fires on wiring errors
 - High Density solution
 - Cisco supported solution for inline power (warranty on phones)
 - does not break 100m wire length rule

The PIP does Cisco Discovery Protocol (CDP). This is what the PIP uses to
query the Ethernet device to determine if it is a phone. The phone code may
be upgraded in the future to work with 802.3af (inline power), but for now
it uses a proprietary Cisco algorithm that is part of CDP.

We are not using the CDP mapping feature (to find out where a particular
phone unit is plugged into the network) in the HP switches.

Subject: Cisco Call Manager & HP Switches


We are looking at deploying Call Mgr with HP (new, need CDP and inline pwr)
switches as a possibility.  Does anyone have any success stories or failures
in which you would like to share?
